Leeteuk and Heechul are total opposites—born just 10 days apart, yet worlds apart in personality.
Heechul – free-spirited, blunt, chaotic, and effortlessly charming. Former leader of the Chocoball group (psycho but cool, charming people) he treats life like a playground. Expressive and affectionate. Often always happy.
Leeteuk – disciplined, diplomatic, and very hardworking and strategic. Former leader of the Milk Club (a support group for artists struggling with depression). Reserved and distant. Prone to depression.
The weakness of one is the strength of the other. And even after 20+ years, Heechul still knows exactly how to make Leeteuk smile. 💛
Just a look at their bond:
Screenshot 1: Heechul’s 2016 IG comment to Leeteuk.
Heechul → Leeteuk: “Good job. I’m filming in my hometown right now. I came to a place where I used to work part-time, and out of nowhere, I thought of you.
Even when I didn’t listen, you always comforted me. Thank you for that. When did people ever clap for us growing up? We grew up clapping for each other. LOL.
We’ve spent 14 years together. That alone is enough and makes me happy. I’m going to sleep now. I have filming again at dawn.
And why am I posting this here instead of sending it privately on KakaoTalk? So my babies (fans) can see it and get excited LOL. SNS is originally for showing off like, ‘See? We’re close~~’ That’s what it’s for 🕺🕺🕺🕺🕺”
